Powerful Drive Train

A Cat C4.4 ACERT engine with twin turbochargers is combined with a new hydrostatic transmission to give you improved fuel efficiency and the most power-dense drive train in its size class. The hystat transmission offers superior maneuverability, faster steering response and greater capability to utilize full blade loads.

Eco Modes

Reduced Idling

Efficiency features reduce engine speed when idling, or shut the machine down after a specified time, to further save fuel and meet idling regulations. Engine Idle Shutdown shuts down engine after pre-set time to reduce idling and help save fuel.

GRADE for Dozers

Cat Connect GRADE technologies help you hit target grade faster and more accurately. Finish jobs in fewer passes, and with less operator effort, saving you time and helping you increase profit.

Cat GRADE with Slope Assist (Standard) helps operators more easily achieve the required main-fall and slope orientation of the blade by automatically maintaining pre-established blade angles for the grade. The system saves time, increases finish quality and reduces operator input. Experienced operators can work more productively and less experienced operators can achieve better quality results more quickly.

Cat GRADE with 3D (Optional – available early 2017) is a factory integrated grade control system that enables operators to improve grading efficiency, accuracy, and productivity in both production dozing and fine-grading applications. The integrated design positions antennas on the cab roof, eliminating conventional blade-mounted masts and related cables. The AccuGrade Ready Option (ARO) is part of the package for added versatility, and AutoCarry™ is included to further boost productivity.

Cat AccuGrade (Optional) is a dealer-installed aftermarket grade-control system that provides increased grading versatility and the ability to scale capacity to changing needs, providing a choice of lasers for 2D flat-plane and slope work, Global Navigation Satellite System (GNSS) control for complex 3D cuts and contours, and/or systems using a Universal Total Station (UTS) for fine and finish grading.

Choose SystemOne™ undercarriage that is designed to work and wear as a system for longer life and lower costs in abrasive or low/moderate impact applications.

A broad choice of track shoe designs and widths help you further optimize your machine for performance and longer life.

Rear Implements

To help you match your dozer to the task at hand, you can outfit your D6K2 with a multi-shank parallelogram ripper, winch or drawbar. A dual control package makes it simple to utilize either a ripper or winch.

Ask your Cat dealer for available options to help you optimize your machine for the work you do.

Forestry Arrangement

Specialized arrangement includes a forestry blade, hydrostatic winch, 360 degree guarding for added protection of the cab and a heavy-duty rear tank guard.

Overview

The D6K2 dozer is smarter and more efficient than ever. It comes equipped with standard Grade technologies like Slope Assist to make it easier for even less experienced operators to get more quality work done in less time. But intelligence is only part of the package – Eco Modes and a new power train deliver up to 17 percent more fuel efficiency, while providing superior maneuverability, faster steering response and greater capability to utilize full blade loads. This dozer also retains its optimal balance and undercarriage design for outstanding performance in finish grading applications. The D6K2 meets Tier 4 Final/Stage IV/Korea Tier 4 emission standards.
